Setting the number of cars in the building. A general guide is that it should no take more Combining high-precision traffi c planning than 30 seconds to travel between the top and bottom fl oors. The number of cars is set in order to ensure that the Using this basic value, the optimum speed for the building is transportation capacity and wait times are maintained within with a building-specifi cation operation plan, selected by adding in such factors as the building’s purpose, service levels at peak times when there is a concentration of character, and service policy. passengers, such as in the mornings and evenings, and during New ELBRIGHT offers the optimum system lunchtime. Below is a general guideline for setting the number ■ Relationship between elevator speed of elevator cars. for your building. and number of floors in building Traffic planning/Group control system Traffic Note that for hotel, approximately two-thirds additional cars need to be allowed as service elevators are not included. ■ 2. Traffi c calculation When deciding on the number of elevator cars, passenger capacity, and service fl oors, traffi c calculation provides numerical data for study. The basic values for traffi c calculation are shown below. Offi ce building : Start of offi ce hours set to be peak for traffi c demand Exclusive owned possession. General office bldg. Hotel : Morning hours for check-ins and evening hours when guests leave or go to dinner set to be peak for traffi c demand The system is able to distinguish between start of offi ce hours, which represent the peak in elevator demand, lunchtime, ■ 3.
